30 amp RV outlet at home
I recently converted from a dual hot water tank setup in my house to a single tank resulting in an unused 30amp double pole breaker. I would like to use this breaker and the 10ga wire to power a TTL-3...

so what people are saying is that with a double pole breaker, both sides must exceed load limit to trip? is that correct?

I would have exactly the same question, but when I think of how 240 doesn't use or need a common, its probably true.
Not true in all cases. A straight 240v load, such as a well pump, won't need a common but not all 240v loads are the same. An electric range may use 240v for heating elements and 110v for lichts and controls. That requires a common because it's an unbalanced load.
Because 240v loads are often unbalanced an overload on one leg will trip a double pole breaker. But I would spend the $5 and replace it with a single pole
